Packaging solutions firm Mondi has developed a fully recyclable polypropylene film for thermoforming applications with a 23% reduction in carbon footprint compared to existing packaging.  

This film is ideal for the thermoforming of flexible firms for modified atmosphere packaging (MAP) and vacuum packaging, which is known for its ability to extend the shelf life of items such as meat and cheese, said Mondi.

The new, coextruded material includes a top and bottom web, with an internal barrier layer that makes up for less than 5% of the entire structure, meaning it qualified as a mono-material and is fully recyclable in existing waste streams. 

Mondi ecosolutions project manager Thomas Kahl said: “Mondi’s view is that packaging should always be fit-for-purpose –– paper where possible, plastic when useful –– and sustainable by design. The challenge with this project was to maintain the functionality that is key to such applications, including excellent oxygen and moisture barriers, and high puncture resistance –– while also enhancing the package’s recyclability. The latter factor was vital as Mondi continues to support the principles of a circular economy.
